Recently, I have always encouraged my close friends to get Mac or iMac for nearly the price of powerful Window PC. I introduced them to look at apple.com and they saw the ads regards "I'm Mac & I'm PC" commercial. Then, we started to have the conversation in comparison. They shown me their laptop running a program called "Easy Wifi Radar" and could get free open Wifi access. But unfortunately, not my MacBook Pro though! So, is anyone out there please kindly advice me, if there is some similar software like that running for MacOSX for free too?
